I irrigated by sinuses and the saline went to my ear, now my ear is popping and hurting?

See below: Problems like these can only be correctly handled by your doctor in person. He/she needs to listen to you, perform an examination and possibly run labs or other tests. That's the only way he/she can find out what's going on and what to do about it.

Fluid in ear: Ask your primary doctor before following any advice here. An over the counter nasal decongestant spray like afrin will usually help to drain te fluid from the ear through the eustachen tube located in te back of your nose.
